[英]How do I fix this code to display the correct message after an upload?
我在下面的代碼中檢查文件是否成功上傳,失敗或取消:
if (success === 1){
result = '<span class="imagemsg'+imagecounter+'">The file was uploaded successfully</span><br/><br/>';
$('.listImage').eq(window.lastUploadImageIndex).append('<div>' + htmlEncode(imagefilename) + '<button type="button" class="deletefileimage" image_file_name="' + imagefilename + '">Remove</button><br/><hr/></div>');
displayInfo = replaceForm;
}
else if (success === 2){
result = '<span class="imagemsg'+imagecounter+'"> The file upload was canceled</span><br/><br/>';
displayInfo = updateForm;
}
else {
result = '<span class="imagemsg'+imagecounter+'">There was an error during file upload</span><br/><br/>';
displayInfo = updateForm;
}
但是我有一個JavaScript函數,該函數在PHP腳本中將其輸出如下:
<script language="javascript" type="text/javascript">
window.top.stopImageUpload(<?php echo $result ? 1 : 2; ?>, '<?php echo $_FILES['fileImage']['name'] ?>');
</script>
現在,如果文件成功上傳,則顯示正確的消息,如果取消,則會顯示正確的消息,但問題是,如果文件上傳失敗,則顯示取消消息,而不顯示上傳消息時的錯誤。 我試圖更改上述代碼的一部分,因此將如下所示:
...<?php echo $result ? 1 : 2 : 3 ?>..
但這給我一個錯誤。 我的問題是如何更改以上代碼,以便在文件上傳失敗時能夠輸出正確的消息?
有什么錯誤?
您的三元語法不正確: http : //davidwalsh.name/php-shorthand-if-else-ternary-operators
正確的語法是:
echo ( <condition> ) ? <event if true> : <event if false>;
您還有其他活動!
$.ajax(
{
url: _spPageContextInfo.siteAbsoluteUrl + "/_api/Web/Lists/getByTitle('" + libTitle + "')/Items",
type: "GET",
contentType: "application/json;odata=verbose",
headers: {
'Accept': 'application/json;odata=verbose',
'X-RequestDigest': $("#__REQUESTDIGEST").val()
},
success: fetchSuccess,
error: onFailure
});
function fetchSuccess(r) {
// How to display the count of "r"
console.log(r.length);
}
function onFailure(r) {
alert("Error + r + working");
}
